Interesting moral question. I don't know if i could rest easy doing that. Nobody knows till they are actually in that position. Edit: Sorry I forgot I is an 'ard man right. I would sleep fine bruv. brap brap.
I can see why people think its crazy or excessive but Should we allow criminals to freely wonder the streets stealing what ever they like. Because thats what happening in london now. how much should a criminal steal from you before you say enough is enough?
The problem is, this world you've constructed where only a mugger is your problem in life and therefore a gun is a solution is flawed. The idea that a gun is a solution is also flawed and we'll go through each point.
Your solution to muggers, could if you pardon the pun backfire. During an argument your girlfriend/wife could lose her rag, take the gun and shoot you, 'Oh no! The mugger wasn't the only potential hazard'.
Or perhaps you misplaced the gun and your toddler child picked it up and shot your wife/gf or even yourself.
Or maybe you've had a very depressing day, normally suicide would seem difficult, but good for you there is a gun on standbye, that's deadpan sarcasm, I hope no one kills themselves but guns make it easier.
Or perhaps a kind neighbour brings the post around after it was delivered to the wrong address. And because you have this same paranoid outlook to your follow man you see him as a threat and shoot him
Guns in the US hardly ever protect anyone ever, they tend to cause murders that are unnecessary, but let's say even if you did come into a conflict with someone and killed them, are you prepared to be charged with murder, manslaughter and do you think you have fair reason to claim self defence?
Also your idea that criminals don't get guns because they don't need to is obviously flawed too. Because trust me every wanna be gangster is wanting to flash a gun. And your idea that making guns easier to own is going to help law abiding citizens over violent criminals is flawed. Because guess what, do you know who wants to carry a gun, a violent criminal, normies tend to frown on it. And if a violent criminal knows a law abiding citizen might be carrying a gun, he isn't going to threaten him, he'll kill him and then take his possessions.
Essentially more guns equates to more death and destruction no matter who has them.
